  15. Threat Actor: An individual, group, or organization responsible for carrying out cyber threats or attacks.
  16. Virus: Malware that can replicate itself and spread to other files and systems.
  17. Worm: Self-replicating malware that spreads independently across systems and networks.
  18. Zero-Day Vulnerability: A security flaw or weakness in software or hardware that is not yet known to the vendor or public, making it a target for exploitation by attackers.
  19. Zombie: A compromised computer or device controlled by an attacker without the user's knowledge.

Security Measures and Tools:

  2. Cryptography: The study and practice of securing communication and data by encoding it into an unreadable format.
  3. Data Encryption Standard (DES): A widely used symmetric-key encryption algorithm.
  4. Data Loss Prevention (DLP): Strategies and tools used to prevent the unauthorized leakage of sensitive data.
  5. Firewall: A network security device or software that monitors and filters incoming and outgoing network traffic to protect against unauthorized access.
  6. Intrusion Detection System (IDS): A security tool that monitors network traffic for suspicious activities and alerts administrators to potential breaches.
  7. Intrusion Prevention System (IPS): A security tool that actively blocks or prevents suspicious network traffic or attacks.
  8. Mobile Device Management (MDM): Solutions for managing and securing mobile devices within an organization.
  9. Multi-Factor Authentication (MFA): An authentication method that requires users to provide two or more separate authentication factors for added security.
  10. Penetration Testing: The process of simulating cyberattacks to identify and address vulnerabilities in a system or network.
  11. Pentesting Tools: Tools and software used by penetration testers to identify vulnerabilities.
  12. Perimeter Security: Security measures that protect the outer boundary of a network or system.
  13. Web Application Firewall (WAF): A security system designed to protect web applications from attacks.

Security Concepts and Strategies:

  1. Cyber Hygiene: Best practices for maintaining good cybersecurity habits, including regular software updates and secure password management.
  2. Cyber Resilience: The ability to prepare for, respond to, and recover from cyberattacks or security incidents.
  3. Cyber Threat Intelligence: Information about potential cyber threats, including attack vectors, tactics, and threat actors, used to enhance cybersecurity defenses.
  4. Cybersecurity Analyst: A professional responsible for monitoring and analyzing security threats and incidents.
  5. Cybersecurity Awareness: The level of knowledge and vigilance regarding cybersecurity among individuals and organizations.
  6. Cybersecurity Framework: A set of guidelines, best practices, and standards for managing and improving cybersecurity.
  7. Cybersecurity Policy: A set of guidelines and rules governing an organization's approach to cybersecurity.
  8. Cybersecurity: The practice of protecting computer systems, networks, and data from security breaches, attacks, and unauthorized access.
  9. Data Classification: The categorization of data based on its sensitivity and importance for security purposes.
  10. Incident Response Plan (IRP): A documented strategy and procedures for responding to security incidents.
  11. Incident Response: The structured process of identifying, managing, and mitigating security incidents and breaches.
  12. Information Security: The practice of protecting information from unauthorized access, disclosure, alteration, or destruction.
  13. Least Privilege: The principle of granting users or systems only the minimum access or privileges required to perform their tasks.
  14. Risk Assessment: The process of identifying and evaluating potential security risks and vulnerabilities.
  15. Security Policy: A documented set of rules, guidelines, and procedures governing an organization's cybersecurity practices.
  16. Security Token Service (STS): A service that issues security tokens for authentication and access control.
  17. Security Token: A physical or digital device that generates one-time codes for authentication or access control.
